. I Be it known thatI, Evnnn'rrtcnnssn, a citizenuof the United Statesof America, residing at Omaha,- in the 1 county "of Douglas and State ofNebraska, have invented certain new and useful. Improvements 1in. WindowFranies,=of which thexfollowing isa specifi cation, reference being had.therein to themei companying drawing. 1

The invention relates towavindow nfranres and; has for its object toprovideia devicefof this character so constructed, that the sashes, bothlower and upper maybe easily and quicklyremovedfrom the frame. i

\ 1 all further object is to provide; a window frame so .constructedthatthe inside stops may be jremo vedpthereby allowing ithe re moval ofvthelower sash, afterf'which 'por-' tionsof the frame amb may be pivoted inwardly so-that the pairtingstrips: carried the pivotedflportions;iofthejambmay be moved inwardly to La ipositionxwherethey will .:allow theremovaluof the upper. sash.

A further object is to provide a window frame having verticallyxpivotedjamb portions which carry parting strips and so pivoted that theys maybe moved inwardly for allowingremovalof the upper sash. Also to provideinside stops having L-shaped hooks adapted to engage apertures in thepivoted portions of the jambs for holding said pivoted portions inposition, said L-shaped hooks being moved out of engagement with thepivoted portions of the-j ambs by forcing the inside stops upwardly.Also. to provide a spring actuated member carried "by each of the stopsfor engaging an aperture in the window, frame forholding the stops inlocked position.

With the above and other objects inview the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention. v

Y :Iteferring t'o the diiawings, :the nuniera1 1 designatesthe a'wi'ndow frame and the weightwboxes thereof. ii The windowframe 1 is ofanconventional constructionwiththe exceptionnthat. the portions 3/ofthew indow jamb. 4' 'are hinge'dly; connected to; ithe faciii-g6 attheir:upper and'lower ends so that, said portions 3 5 imay be dow frame bymeans of" screws 9. The leaves 10 of the hinges 7 are secured to theupper ends of the j amb sections 3'by means 7 pivoted inwardly; Thehinge pi'ntles 6." are carried by hinges 7 and 8. The hinges 7 are atthe upperendsof the pivoted Ijamb sections 3 I and. their leaves :8 aresecuredto the top of; the' winof screws 11, said portions 3 beingsecured adjacent the ends of the hinge leaves 10 so that when jambportions 3 are pivoted outwardly, they will be disposed adjacent 'theinside faces 12 of'the window frame and whenpivoted inwardly they willengage the faces 13 within the weightboxes 2 as shown in Fig. 3.The'lower pintles 6 are carried by the hinges 8, which hinges have theirleaves 14 secured tothe window sill by means of screws 15and theirleaves 16' securedto the bottom endof the pivoted jamb sections 3 bymeans of screws 17. The lower portions of the pivoted j amb. sections 3are secured to the leaves 16 adjacent their ends so that when thepivoted jamb sections are pivoted outwardly, they will be disposedadjacent the inside faces 12 of the window frame, and when in normalposition as e 9 shown in Fig. 3, they will engage the surfaces 13'within' the weight boxes. The

- parting strips 19 are carried the pivoted jamb sections 3 and betweenthe parting strips 19 and the inside stops 20, thelower sash 21isadapted to move when said sash is j being raised or lowered. Upper 2 2slides upwardly and downwardly between the parting strips 19 and theoutside stops 23.

The inside stops 20 are provided on their inner faces with plate carriedhooks 23:,

1 which hooks are adapted to be received by. apertures "25 inplates26,'which" plates are carried by the pivoted jamb sections 3. By

providing hooks it will be seen that the inside stops 20=may be removedby simply forcing the stops upwardly "until the hooks 24' are iinovedout of engagement with the apertures 25, after which the lower sash 2I-may be removed, and the sash cord pins 27 pulled out Jot. engagementwith the v aper tures 28 in the sash 21. I been moved it will be seenthatthe parting strips 19 maylbe'moved out ofLeng-agement with theuppensash" 22 by: pivoting putwardly the pivotedjalnb sections *3, afterwhich'th'e upperl sash 22ymay be easily re moved. When it is desired toreplace the sashes,;'theoperation-is reversed; .Inside stops 20,arenormally held against displacement by means of plate carried pins 29,said pins: being slidable in plates and normally. :held in engagementwith the apertures 30 in the pivoted jamb sectionsB-by springs 31,'whichhave been 'bowed by the outward movement Ofithe-EpinsQthen raiseupwardly; so that-the hooks Qetmay he re- ,moved .throughlthe'apertures25 inplates 26! j r v Stops 20 having From the above it will beseenv that a window frame is provided wherein the lower and upper sashmay be easily and quickly removed and one wherein the sashes may beeasily and quickly replaced.

If so desired fillets 38 may beplacedin the bottoms of the weight boxes2 for" limiting the inwardmovement of the pivoted j amb sections 3.However, the inside stops are preferably made wide enough so ithat theywill engage. the surfaces 34=wso rthatthe 7 stops will prevent theinward pivotal action ofthe'pivoted jamb sectio'nsBL a 1 The invent-ionhaving been set forth' what is claimedas new and useful is I 3 Thecombination with a. window fram having upper and lower sashes slidablymounted therein 'between iouter stops, i inner stops and parting strips,said parting strips being carried by pivoted jamb sections,;said

jamb sections being pivoted adjacent the innercfacing of the frame, "theinner stops being provided'fwith L-shaped lugsiadapted ing th'ellshapedlugs to be moved out-0r engagement with; the plates- :of the pivotedjamb. sections, and spr ng actuatedpins cart riedvby the inside stops"and adapted to en to engageplates carriedby thepivoted jamb l sections,said inside stops terminating spaced fromjthe "top of the frame therebyallow-' gage apertures inethe pivotedjambsections forcholding the"L-shaped lugs inenga'gement' with the plates of the pivoted jambrsections.
